这里我将讲解一下从0搭建一个electron最简版架子,以及如何实现打包自动化更新
之前我有写过两篇文章关于electron框架概述以及 常用api的使用,感兴趣的同学可以看看
Electron桌面应用开发
Electron桌面应用开发2
官方文档:https://www.electronjs.org/zh/
创建一个文件目录
mkdir my-electron-app && cd my-electron-app
yarn init
然后,将 electron 包安装到应用的开发依赖中。
yarn add --dev electron
{
"name": "my-electron-app",
"version": "1.0.0",
"description": "Hello World!",
"main": "main.js", // 入口文件
"author": "Jane Doe",
"license": "MIT",
"scripts": {
"start": "electron ."
},
"devDependencies": {
"electron": "^27.0.3",
}
}
main.js
const createWindow = () => {
const win = new BrowserWindow({
width: 800,
height: 600
})
win.loadFile('index.html') // 加载index.html
}
index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<!-- https://developer.mozilla.org/zh-CN/docs/Web/HTTP/CSP -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'">
<title>你好!</title>
</head>
<body>
<h1>你好!</h1>
我们正在使用 Node.js <span id="node-version"></span>,
Chromium <span id="chrome-version"></span>,
和 Electron <span id="electron-version"></span>.
</body>
</html>
yarn start
就可以启动起来,这是最简版的框架
做mac的打包需要开通苹果开发者账号,购买证书,打包需要签名,这里购买和配置的流程很复杂就不做过多赘述,都搜的到。
其实windows也需要签名 证书,但是不提供也可以打包
打包和自动升级用到了官方提供的两个工具
打包:electron-builder
升级:electron-updater
electron-builder官方文档地址:https://www.electron.build/configuration/win#WindowsConfiguration-certificateSubjectName
如果觉得英文看着不方便,有大神中文总结了一下,地址:https://blog.csdn.net/qq_38830593/article/details/89843722
首先下载这两个库:
yarn add electron-builder -D
yarn add electron-updater
package.json里做参数配置
看build参数,各个参数对照着官方文档

</script>
执行yarn build
之后,会生成安装包 和 yml文件
yml文件是内部做检测更新使用
version: 1.0.0
files:
- url: electron-test-1.0.0-arm64-mac.zip
sha512: YFebRa4hFb0eq7JBHtIbe6zpEm59b3uR0NaKJJaY5M7G7ZfCoFIWJl/N3cDzSvPK1vWSgeGTRwxteHmwV7PXBQ==

releaseDate: '2023-11-05T08:56:32.685Z'
我们需要把这三个文件放在 对象存储服务器上
只要提供的更新地址拼接上 latest-mac.yml文件的 可以访问到就可以
这样就可以做更新了
如果做测试,本地启动一个服务
//更新连接
autoUpdater.setFeedURL(
'http://127.0.0.1:5500/build'
)
